the objective of the study was to determine by HPLC whole body aminoacid compositions of shi drum after a 4 months long period according with two lipid/carbohydrate ratio (EE/NFE):1.0 vs !.5. Total and essential AA amount were found significantly higher in EE/NFE 1.0 fed fish as well as LYS and LEU content resulting in an higher crude protein retention. Results suggest that low dietary EE/NFE ratio increases protein feed efficiency by reduction of catabolic oxidation of almost two essential amino acid.

Abstract
the objective of the study was to determine by HPLC whole body aminoacid compositions of shi drum after a 4 months long period according with two lipid/carbohydrate ratio (EE/NFE):1.0 vs !.5. Total and essential AA amount were found significantly higher in EE/NFE 1.0 fed fish as well as LYS and LEU content resulting in an higher crude protein retention. Results suggest that low dietary EE/NFE ratio increases protein feed efficiency by reduction of catabolic oxidation of almost two essential amino acid.
